/LOW PRESSURE SYSTEM OVER CALIFORNIA AND NEVADA. THESE FEATURES WILL
BE APPROACHING THE AREA FROM THE UPPER MIDWEST TO THE CENTRAL
ROCKIES BY WEDNESDAY MORNING. AT THE SURFACE, LOW PRESSURE WAS
DEEPENING OVER NORTHWEST KANSAS IN RESPONSE TO THE APPROACHING
NORTHWEST TROUGH. THE SHORT TERM MODELS SHOW THE SURFACE LOW MOVING
OFF RAPIDLY TO THE EAST TODAY AS A PIECE OF SHORTWAVE ENERGY EJECTS
OUT OF THE NORTHWEST TROUGH AND HEADS EAST.
LOW LEVEL WARM ADVECTION WAS ONGOING ACROSS WESTERN KANSAS THIS
MORNING TO THE EAST OF THE LOW. WINDS HAVE BEGUN TO VEER WITH TIME
EARLY THIS MORNING AND SHOULD CONTINUE TO DO SO THROUGH MID MORNING.
AS THE SURFACE LOW MOVES EAST, A COLD FRONT WILL DROP SOUTH ACROSS
CENTRAL AND WESTERN KANSAS FROM MID TO LATE MORNING. TEMPERATURES
SHOULD RISE SOME THIS MORNING AHEAD OF THE FRONT BUT WILL LEVEL OFF
OR GRADUALLY FALL BACK THIS AFTERNOON AS COLD AIR ADVECTION
INCREASES. TEMPERATURES SHOULD TOP OUT IN THE LOWER 40S ALONG I-70
WITH UPPER 40S TO NEAR 50 DEGREES POSSIBLE ALONG THE OKLAHOMA BORDER.
AS THE UPPER LEVELTROUGH MOVES INTO THE CENTRAL PLAINS TONIGHT, THE
LOW TO MID LEVELS OF THE ATMOSPHERE WILL BEGIN TO MOISTEN UP WITH
LIGHT SNOW DEVELOPING OR MOVING INTO SOUTHWEST KANSAS GENERALLY
AFTER MIDNIGHT AS A MID LEVEL BAROCLINIC ZONE MOVES SOUTH INTO
WESTERN KANSAS AND FRONTOGENETIC FORCING INCREASES. TEMPERATURES

UPPER TROUGH SHOULD BRING SOME CLEARING SKIES DURING THE OVERNIGHT

WILL BE LOCATED EARLY THURSDAY MORNING ALSO. GIVEN CLEAR SKIES,
LIGHT WINDS AND EXPECTED SNOW COVER WILL BE STAY SEVERAL DEGREES
BELOW THE COOLER GUIDANCE FOR LOWS, ESPECIALLY EAST OF DODGE CITY.
AN UPPER LEVELRIDGE AXIS WILL BECOME ESTABLISHED OVER THE WEST
COAST LATE WEEK AND A NORTHWEST FLOW IS EXPECTED ACROSS THE
